ZURICH—The World Cup is proving to be a trying period for former French soccer captain and current commentator Patrick Vieira.

On the opening day of the tournament, the studio on Rio de Janeiro‘s glamorous Copacabana beach was pelted with rocks by protesters. Vieira, who is analyzing matches Britain’s ITV broadcast of the games, was uninjured by the attack.

On Tuesday, Vieira’s month got worse. Switzerland’s tax office said it would send banking information linked to Vieira to its counterparts in Paris, who are investigating the World Cup winner who has now retired from playing.

The Swiss federal tax authority gives administrative assistance under a bilateral double taxation treaty between France and the Alpine country and intends to pass over Vieira’s details. The French authorities didn’t comment on the request.

Vieira, who declined to comment on the matter, enjoyed a trophy-laden career in England with Arsenal and Italy with Juventus and Internazionale after winning a World Cup with France in 1998. He is one of the most respected soccer pundits in the U.K.

Switzerland made public the planned transfer of banking documents in a weekly list of official announcements. The list showed that Switzerland had received an official request, but since the content of requests for administrative assistance is confidential, it couldn’t say whether Vieira was suspected of doing anything wrong.

Vieira has 30 days to oppose the handover of his banking details. At least by then he will have finished giving his views on this year’s tournament.
